TO BACCO-R'ESWEATER.

SPECIFICATION forming part vof Letters Patent No. 302,011, dated July 15, 1884.

Application tiled October 1, 1883. (No model.)

.To @ZZ whom t may' concern:

Be it known that I, BRUNO MARTIN, of East Saginaw, in the county of Saginaw and State of Michigan, have invented new and useful mprovements in Tobacco-Resweaters; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of -this specification.

This invention relates to certain new and useful improvements in devices for resweating tobacco, and is especially designed as an improvement upon the invention described in Letters Patent issued to me May 22, 1883, and numbered 278,029.

The invention consists in the peculiar construction, combinatioma'nd operation ofthe various parts, as more fully hereinafter described.

.water on all sides.

Figure l is a perspective view of my completed device. Fig. 2 is a vertical central cross-section. Fig. 3 is a detached and vertical longitudinal section of .the oil and water reservoirs and their attachments.

In the accompanying drawings, which form a part of this specification, A represents a closed water-tank supported upon suitable brackets upon the side of the sweatbox B, which in turn, is supported upon the table C.

D is an oil-tank, which is suspended within thewater-tank so as to be surrounded with The water-tank is filled through an orifice, a, and is provided with a water-gage, b, and the oil-tank is filled through the pipe c, and this iu turn is provided with an indicating-gage, d, these gages affording at all times knowledge of the height of water or oil in their respective tanks. A pipe, E, conducts oil from this tankl to the bottom of the illed with water strongly impregnated with sal-ammoniac and soda, and the hydrocarbon from the tank D being conducted to the bottom of such tank, and being of lighter gravity,

rises through such impregnated liquid and enters the air-chamber, compressing the air therein, which forms acushion to force the carbon down through the pipe H to the burner. The hydrocarbon, in passing through the liquid in the tank, becomes chemically purified from such impurities as cause it, when carriedv to the burner, to spit or sputter, thereby supplying a purehydrocarbon to the vapor-burner which burns without sputtering or making perceptible noise. This tank is Vsupplied with a waste-cock, t', to enable the same to be emptied when desired. A

I is a pipeleading from the water-tank A to the tank J, which is provided with the iioatvalve K, by means of which the height of water in this tank and its outiiowtherefrom are regulated; and the branch pipe L is provided with a cock, k, which governs the flow of wa terthrougli such pipe to a tank which surrounds the burner.

M is an outflow pipe from the tank J,

copducting water through the coil N, which i surrounds the boiler O, and discharges the same into such boiler at any convenient point below the water-level in the tank J. Through this boiler, and opened at its lower end and closed at its upper one, passes the conical tube P, its lower end being presented immediately above the burner Q, which is of any of the known constructions of hydrocarbon -vapor burners. l

Z is the top part ofthe boiler, removable from the lower part. and forming, when in place, a steam-tight joint, its lower edge reaching below the water-line to form a seal. The steam generated in thel boiler is made to escape through a removable rose, m, situated in the top of the boiler.

Surrounding the boiler on all sides is a sheet-metal shield, R, which forms a chamber between its inner and outer walls, and which serves lthe double purpose of confining, the iiames from theburner to the sides of the boiler, and also to protect the wood-work of the table; and to still more rinsure the safety of the device, an annular tank or trough, a, is formed in its bottom, which is filled with water through the pipe L, which forms a branchof the pipe I.

The sweat-box is constructed as described IOO in my aforesaid Letters Patent, and the operation of the device will be readily understood from the description of its construction.

One of the objects of this improvement is to prevent the sputtering, as it is ordinarily termed, and disagreeable noise attending the use of such devices employing hydrocarbonvapors for heating purposes, and furnish a device which delivers the hydrocarbon to the burner so thorougly puried as to avoid these obnoxious features.

What I claim as my invention is- 1. In a device for resw'eating tobacco, and in combination with the water-tank A, surrounding the oil-supply tank D, the tank J, provided with a float-valve receiving Water from the tank A and delivering the same to the boiler 0, such tank J, with its float, at all times regulating the height of water in the boiler, and being situated outside thereof, substantially as and for the purposes set forth.

2. A boiler for atobaeco-resweating device, projecting into the chamber thereof, provided with the removable top Z and removable rose m, and having through the same theA conical tube I), immediately over the burner Q, substantially as specified.

3. In atobaeeoresweating device, the shield R, located Within the table surrounding the boiler, and adapted to direct the flames of the burner against and around such boiler and the coil of feed-pipe surrounding the same, and provided in its bottom with an annular watertank fed from the tank A, substantially as and for the purposes described.

4. In combination with a resweating device, its boiler` and hydrocarbon-vapor burner, the tanks A, D, F, and J, ywith their connectingpipes to the boiler and burner, arranged and operating substantially as specified.

BRUNO MARTIN.
